Bluetooth paired my iPhone (up to date software) with the cars system. All contacts down loaded and displayed on screen. On leaving and returning to the car - only contacts A and B available.
Dealer had a look and has updated the screen software. Unfortunately still the same problem. If the devices are un paired and then paired again, all contacts are listed. Leaving the car and then returning - only contacts A - B display!
No problem with my previous Cactus and the same phone.
Guess a bug for Citroen to sort
